RUBBER-TIRE ARMOR.

Specification of Letters Yatent.

Patented May 111, 1915.

Application filed August 21, 1914. Serial No. 857,856.

To all whom it ma concern Be it known t at I, FRANK H. TALBOT, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Rubber-Tire Armor, of which the following is a specification.

My invention relates to vehicle rubber.

tires and more particularly to that class of rubber tires known as pneumatic automobile tires.

The objects of my invention are; First.

' To aiford anarmor or 'protector for the pneumatic tube of said tires against any possible puncture of said tube in the actual; use thereof. Second. To overcome the possibility of blow-outs occasioned by a rupture of the outside tire, which occurs most usually in the side of the tire. Third. To strengthen the outside tire and keep it constantly expanded.

I- accomplish the aforesaid objects by means of the mechanism hereinafter described and also illustrated,-in which illustrations like reference characters represent like parts inall figures.

Figure 1 is a perspective view of a portion of an automobile wheel, with certain parts of the tire broken away in order to expose to viewcertain other parts thereof.-

Fig. 2 is a perspective view of a detached portion of an outside tire showing in section the peculiar shape of the longitudinal edges thereof. Fig. 3 is a perspective view of a detached portion of my invention which consists of a steel armoror casing adapted to neatly cover the pneumatic tube of said tire, said view showing the manner in which the free ends thereof slidably engage each other. Fig. 4 is a perspective view of a detached portion of the pneumatic tubeof said tire.

Fig. 5is an elevation of a screw adapted to give direction to the overlapping ends of my invention in their movement one upon the other by fixedly engaging a perforation in theone and slidingly engaging an alining slot in the other.

A is a portion of an. automobile wheel.

B is the outside tire thereof. C is my aforesaid invention. D is the pneumatic tube of the tire of said wheel. 1 is a loopin the under-lapping end of the armor, said loop being effected by slitting the armor transversely in two parallel lines and then by pressing said loop outwardly, said loop said also being adapted to permit the finger 3 to pass" slidingly underneath it. 2 is a pocketshaped loop in the undeielapping end -0 said armor, said loopbeing effected by the use of a single transverse slit in said armor and then. bypressing said loop outwardly, said loop being adapted to permit the end 4 of-said finger to slidingly pass underneath it. 5 is a slot cut longitudinally through said finger, said slot being adapted of the horizontal abutting edges, spearshaped in section, of said outside tire. 8 is one of the horizontal abutting out-turned edges of said armor. v 9 is one of the inturned edges of the metalrim of said wheel.

gage said inturned edge 9, and said out-.. turned edge 8 is adapted to engage said spear-shaped edge 7. Said pneumatic tube D when inflated is adapted to expand said to receive the end of the screw 6. 7 is one Said spear-shaped edge 7 is adapted to enoutside tire B and impart resilience thereto,

and said armor G is adapted to augment the resilience of said tube, to protect it from punctures, to assist in expanding said out- I1{evolution of said wheel, every portion of said armor is brought into action. When the interlocked ends of said armor are forced either toward or away from each other, the finger and loop mechanism. de-. scribed above yieldably accommodates itself to the strain. If a puncturing obstacle is so side tire and to prevent blow-outs. Said encountered, the cutting point or edge there H of can penetrate only to said armor and is there arrested altogether or else turned aside. If a rupture occurs in the side of the'outsidetire, said armor, intervening between said rupture and'said pneumatic tube, prevents a blow-out. In addition to all this,

- said tube being protected at every vulnerable point, there is at all times, regardless of punctures and ru tures of the outside tire a combined resilience of saidtube and stantly expanded and in working condition.

armor that keeps said outside tire con- Having thus described my invention in detail, by illustrations and as a working mechanism, what I claim is In a rubber vehicle tire, an armor, 0on sisting of any suitable metal formed and fashioned into a circular tube, having its inner side slitted longitudinally, the longitudinal edges of said slit being out-turned, one end of said tube having on its upper side a loop and a loop-shaped pocket, the other end of said tube having a longitudinally-slotted finger-shaped extension therefrom, in combination with a screw, said loop and said loop-shaped pocket being adapted to receive said finger-shaped extension slidingly, said screw. being adapted to fixedly engage a perforation through said loop and slidingly engage the slot through said finger-shaped extension, said outturned edges being adapted to engage the longitudinal edges of the outside portion of said tire.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FRANK H. TALBOT.
